She allegedly attempted a murder-suicide by drowning one baby and suffocating the other, poisoning her 4-year-old daughter by putting some kind of medicine in her drink, then slashing her own wrists. The child is listed in stable but guarded condition at St. Christopher’s Hospital for Children, reports the Associated Press.

Ron Smalls told WPVI-TV that the couple had been experiencing marital strife, but she refused to attend counseling:

“We’ve had some problems and I’d suggested therapy for both of us,” he said. “She didn’t think it was important.”

The children were discovered by their father when he arrived home at approximately 4:00 p.m. He called 911, telling the dispatcher that his wife had murdered his babies. Police quickly arrived on the scene and the babies were pronounced dead at approximately 4:10 p.m.

Upon arrival, Stacey Smalls allegedly said, ” I harmed my babies.”

According to NBC10, Stacey Smalls left notes next to the children, one saying, “This is why I killed your kids.” The detailed notes were left for her husband, who is a correctional officer, explaining her anger upon finding out on Mother’s Day that he was allegedly having an affair with Stacey’s daughter from previous relationship.

“She had something that she felt was justification but there is no justification… it’s a tragedy two young babies dead and there is no excuse for that,” said Police Commissioner Charles Ramsey.

Mrs. Smalls changed her Facebook status from “married” to “divorced” earlier this month and also put her marital issues out there for the world to see.
